I like to imagine all my guys died after completing a utopia for one. One of an organized large underground base having every material laid out in it's own pile. Linking up to the outpost only connected to the surface of the moon through door covers that hide the large pit dug to bedrock, that could easily get rid of any venator pests on the doors. The other guy died in his large castle filled with many citrifuges. The walls did keep out the venators though .
